在Flex中如何格式化日期在Flex的应用中，我们有时候需要格式化一下日期的格式，该如何做呢
import mx.formatters.*;private var myDataate=new Date(); private function changeDatas():void{// 格式化函数var myDateFormatterateFormatter=new DateFormatter();// 定义日期格式myDateFormatter.formatString="YYYY-MM-DD JJ:NN:SS";mx.controls.Alert.show(myDateFormatter.format(myData));}
Flex3语言参考手册中，关于DateFormatter的formatString是这样解释的：
The following table describes the valid pattern letters:
Pattern letter
Description
Y
Year. If the number of pattern letters is two, the year is truncated to two digits; otherwise, it appears as four digits. The year can be zero-padded, as the third example shows in the following set of examples:
YY = 05 YYYY = 2005 YYYYY = 02005
M
Month in year. The format depends on the following criteria:
If the number of pattern letters is one, the format is interpreted as numeric in one or two digits. If the number of pattern letters is two, the format is interpreted as numeric in two digits. If the number of pattern letters is three, the format is interpreted as short text. If the number of pattern letters is four, the format is interpreted as full text.
Examples:
M = 7 MM= 07 MMM=Jul MMMM= July
D
Day in month. While a single-letter pattern string for day is valid, you typically use a two-letter pattern string.
Examples:
D=4 DD=04 DD=10
E
Day in week. The format depends on the following criteria:
If the number of pattern letters is one, the format is interpreted as numeric in one or two digits. If the number of pattern letters is two, the format is interpreted as numeric in two digits. If the number of pattern letters is three, the format is interpreted as short text. If the number of pattern letters is four, the format is interpreted as full text.
Examples:
E = 1 EE = 01 EEE = Mon EEEE = Monday
A
am/pm indicator.
J
Hour in day (0-23).
H
Hour in day (1-24).
K
Hour in am/pm (0-11).
L
Hour in am/pm (1-12).
N
Minute in hour.
Examples:
N = 3 NN = 03
S
Second in minute.
Example:
SS = 30
Other text
You can add other text into the pattern string to further format the string. You can use punctuation, numbers, and all lowercase letters. You should avoid uppercase letters because they may be interpreted as pattern letters.
Example:
EEEE, MMM. D, YYYY at L:NN A = Tuesday, Sept. 8, 2005 at 1:26 PM
The default value is "MM/DD/YYYY".
